# Rhino.Runtime namespace

Assembly: [RhinoCommon](https://developer.rhino3d.com/api/rhinocommon/assembly/rhinocommon.md)

## Interfaces

- [IPlatformServiceLocator](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.iplatformservicelocator.md): Get platform specific services that are used internally for general cross platform funtions in RhinoCommon. This includes services like localization and GUI components that have concrete implementations in the RhinoWindows or RhinoMac assemblies
- [IShrinkWrapService](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.ishrinkwrapservice.md): Internal interface used by ShrinkWrap functions
- [IZooClientUtilities](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.izooclientutilities.md): Interface implemented in ZooClient and added to Rhino via dependency injection
- [IZooClientUtilities2](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.izooclientutilities2.md): Additions to [IZooClientUtilities](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.izooclientutilities.md). Implemented in ZooClient alongside that interface and discovered by casting the injected service. New members go here rather than on [IZooClientUtilities](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.izooclientutilities.md): that interface is public, so adding to it is a breaking change for anything else that implements it.

## Enums

- [CloudHostUtils](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.cloudhostutils.md): Public wrapper exposing the cloud entitlement gate to cross-platform consumers. Resolves the platform service lazily on first use; falls back to a no-op host when no platform implementation is registered.

- [DocumentCollectedException](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.documentcollectedexception.md): Represents the error that happen when a class user attempts to execute a modifying operation on an object that has been added to a document.
- [HostUtils](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.hostutils.md): Contains static methods to deal with the runtime environment.
- [Interop](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.interop.md): Contains static methods to marshal objects between RhinoCommon and legacy Rhino_DotNet or C++.
- [LicenseStateChangedEventArgs](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.licensestatechangedeventargs.md): Passed to LicenseStateChanged event on RhinoApp
- [NamedParametersEventArgs](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.namedparameterseventargs.md): Dictionary style class used for named callbacks from C++ -> .NET
- [NotLicensedException](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.notlicensedexception.md): Exception thrown when calling functions in RhinoCommon and the application is executing without a license
- [PythonCompiledCode](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.pythoncompiledcode.md): Represents scripting compiled code.
- [PythonScript](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.pythonscript.md): Represents a Python script.

- [Skin](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.skin.md): Represents a customized environment that changes the appearance of Rhino. Skin DLLs must contain a single class that derives from the Skin class.
- [TextFields](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.textfields.md): This Class Processes Text Field Functions
- [TextFields.InstanceAttributeField](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.textfields.instanceattributefield.md)

- [ViewCaptureWriter.Pen](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.viewcapturewriter.pen.md)
- [ZooClientParameters](https://developer.rhino3d.com/api/rhinocommon/type/rhino.runtime.zooclientparameters.md): ZooClientParameters is a read-only set of parameters that control the flow of licensing inside ZooClient. Because this class flows through a number of other classes, functions, and UI, it is read-only so that inadvertent changes are not made to the data as it propagates from the caller.
